Kathy/Bri - you're thinking of the Oklahoma City bombing, not 9/11.
There were a handful of children who were on board the hijacked planes.
I don't think there were any children in the towers that day. Fortunately 9/11 wasn't something like "bring your kid to work" day.
Yes children died. I believe I remember hearing that there was actually a day care in the trade Center.
Bri, I believe you are thinking of the Waco bombing... There was a day care center in that building.
Strictly a curiosity question as no victim is more important than children. And it has never been clear to me if children did die in the towers that horrible day. I hope the answer was none.
